-GRAIN-:DRILL.

SPECIFICATION forming part of Letters Patent No. 444,290, dated January6, 1891.

Application filed June 12,1890. Serial No. 355,234. (No model.)

l which the following is a specification.

Our invention has reference to that class of force-feed distributers inwhich avertical feedwheel revolving in a seed-cup is provided in itsopposite sides with two annular channels adapted to feed different kindsor quantities of seed, and combined with a cut-off device by whicheither of the channels maybe brought into use at will.

The improvement consists in the peculiar construction and arrangement ofthe cut-off or wicket which we hinge to a bridge or division plate inthe cup overlying the wheel, so that the wicket may be turned from oneside to the other in order to cover one or the other of the throats orseed=inlets.

In the accompanying drawings, Figure 1 1s a perspective view of ourimproved feeder. Fig. 2 is a vertical cross-section of the same on theline 2 2 of Fig. 1. Fig. 3 is a perspective view of the wicket orcut-off. Fig. 4is a perspective View of the bridge to which the wicketis hinged. Figs. 5 and 6 are vertical cross-sections on the lines 5 5and 6 6 of Fig. 1, showing the manner in which the bridgepiece issecured in position.

Referring to the drawings, A represents the vertical feed-wheel,provided in its opposite faces with the two independent annular channelsa a.

B is a feed cup or case consisting of two complementary halves fastenedtogether and adapted to confine the feed-Wheel between them, the form ofthe cup being such that the seed entering at the top may pass downwardon opposite sides of the wheel into its respective channels, throughwhich it 1s carried by the rotation of the wheel-and continuously delivered at the rear. The construction and operation of these parts areessentially the same as in the feeders now in general use, and beingfamiliar to those skilled in the art and will.

foreign to our invention need not be further described herein.

0 represents a stationary bridge-piece or casting fixed centrally withinthe cup,its lower edge being curved to closely encircle the upper sideof the wheel, so that it serves as a division between the two sides ofthe cup.

D represents the wicket or cut-off to which our invention relates. Thiswicket is hinged at one edge to the top ofthe bridge-piece, so that itmay be turned from right to left to cover and close either side of thefeed-cup at The two channels of the feed-wheel are of different sizes orforms and are adapted for the feeding of difierent kinds of grain or thesame grain at different rates of speed, s0

that by turning the wicket from one side to the other we may permit thepassage of the grain through either side of the wheel at will, at thesame time preventing its passage through the opposite side.

The bridge is cast complete in one piece,with a perforated ear 0 at oneend and with a slotted ear 0 at the opposite end, and is held immovablyin place between the two sections of the feed-cup B. fore the sectionsof the cup are'fastened together, and the sections recessed in theirapproximate faces to receive and interlock with the ends of the bridge,as shown in Figs. 5 and 6. The parts may be constructed in any suitableform, provided only the sections of the cup are adapted to hold thebridge in place The wicket or cut-off is formed, as shown, with journalsor trunnions cl (1' at opposite ends and of appropriate size to enterthe ears of the bridge. The wicket is marked on each side with the nameof the seed or grain which the machine is adapted to distribute whenthat side of the wicket is uppermost, so that the attendant observingthe name which is exposed to view on the plate is prevented fromaccidentally adjusting the wicket in an improper position. The trunnionsof the wicket differ in size and the ears in which they are entered aremade of corresponding size, so that in assembling the parts the workmanis compelled to place the wicket in the proper position-that is to say,in position to The bridge is inserted beexpose the names in the properrelation to the seedenp. The wicket is inserted into its place bysliding it endwise through the slotted ear. hen turned to either sideits escape is impossible.

Having thus described our in vontion, what we claim is- 1. Incombination with the duplex feedwheel, the divided cup, the bridgeconfined between the two parts of the cup and provided with ears, andthe reversible wicket or out-oft provided with journals seated in saidears.

2. In combination with the feed-wheel and cup, the bridge provided withthe perforated and the slotted ear, and the reversible cut-off plateprovided with journals and adapted for insertion in an endwise directionthrough the slotted ear.

v 3. In a duplex seed-distributer, the reversible wicket marked toindicate d-iiferentseeds hands this 27th day of May, 1S90,inthepres- 35ence of two attesting witnesses.
